Thyroid eye disease (TED) represents the most frequent and important extrathyroidal manifestation of Graves' disease. Less commonly the eye changes may occur in euthyroid individuals without a preceding history of thyrotoxicosis, represents approximately 8-21% of TED cases. Patients with the rare combination of primary hypothyroidism and TED are predisposed to severe eye disease and atypical presentation of such patients may delay diagnosis and treatment . The primary importan...

Objective: Thiazolidinediones offer promise as oral insulin-sensitizing agents. Peroxisome proliferator-activated receptor-g (PPARg), a member of the steroid receptor superfamily, play a pivotal role in the differentiation of adipocytic cells. Osteoblasts and adipocytes are derived from common bone marrow stromal cells that play crucial roles in the generation of osteoclasts. Activation of peroxisome proliferator-activated receptor-g (PPARg) induces adipogenic differentiation ...

Objective: Human growth hormone (hGH) stimulates bone formation and have been proposed as therapeutic agents for osteoporosis. We have examined the effects of hGH on femoral and vertebral bone strength in osteoporotic rats.Methods: Thirty-five Sprague-Dawley rats were assigned to study in three groups: (1) Normal rats (without ovariectomy and corticosteroid therapy) (2) Osteoporosis group: ovariectomized (OVX) or with glucocorticoid induced osteoporotic ...

Objective: Estrogen or raloxifen prevent estrogen deficiency-induced bone loss animals and humans. There is a medical need for agent with the positive effects of estrogen on bone and the cardiovascular system, but without the negative effects tissue. So, we investigated the effects of raloxifen on bone strength and cholesterol levels in osteoporotic rats and compared them with estrogen treatment.Methods: Thirty-one ovariectomized (OVX) Sprague-Dawney ra...
